Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed March 21, 1903. Serial No. 148,957.

To all whom it may concern:

Be it known that I, OTTO L. OSTENDORF, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new andusefu-l Improvement in Chairs, of-which the following is a description, reference beingl had to the accompanyingdrawings, whic are a part of this specification.

This invention relatestochairs more particularly to improvements in that class of chairs known as Morris chairs. I

The object of this invention is to produce a chair of the class named having a seat or seat frame and a back or back frame independently adjustable to different inclinations.

A further object of this invention is to produce a chair as above outlined in which the front of the seat may be adjusted to different positions vertically of the chair body and in which the rear of the seat which supports the back frame,which is movable longitudinally of said seat, is supported by a seat supporting member adjustable vertically of the chair body, whereby when the desired inclination is given to the seat the back frame may be adjusted to different inclinations by the person using the chair while seated therein.

These, and other objects, I attain in the chair constructed as hereinafter described in the specification and illustrated in the draw ings presented herewith in which Figure 1 is a side elevation taken on a line inside of one of theside racks, of a chair embodiying this invention: Fig. 2 is a rear view in e back rail is broken away: Fig. 3 is a view looking toward the seat and taken on linev 33 of Fig. 1: Figs. 4 and 5 are views in side elevation of said chair and illustrate different positions to which the back and seat may be adjusted.

Throughout the several views, similar elements are denoted by like characters.

In these illustrations I have shown a simple construction or design of a chair embodying this invention, the body of which consists of two side racks each having a rear ovation of said chair and in this view the 14 connected together by means of a stretcher or rod 15. In order to protect the edges of the series of slots formed in the rear posts against wear a metallic cap 12 is secured to the inner side of each rear post and said cap is slotted so as to correspond with the slots in the rear posts.

The lower ends of the seat supports 14 are formed in the nature of a hook 16 each adapted to engage a pin or peg 17 secured to the seat frame 18 adjacent to its rear end. By means of these series of engaging members the rear of the seat may be adjusted to and of the chair body.

The lower ends 22 of side arms 23 of the back frame, straddle the rear of the seat frame which is formed narrower than the front portion for that purpose and said lower ends of the side arms of the back frame are rovided with pins 24 which extend into s ots 25 formed for that purpose in the seat frame. The back frame by means of pins 24 is supported by the seat frame and rests against the seat frame supports 14 as a fulcrum.v In order to move the back frame to and hold it in different positions each pin 24 outside of the side arms of the back frame carries a forwardly extending seat frame; the forward or outer end of each pin 28 is bent down as shown at 29 to hold the actuating'member in place close to the seat frame. As the tendency of the lower end of the back frame is to move forward, by means of the engaging projections 27 the back frame may be held in the desired position and by means of the actuating members whichare provided at their forward ends with hand grasps 30, the back frame may be moved to different positions by the person using the chair while seated therein.

As shown in Fig. 5, if it is desired, a stretcher 31 may be inserted within the slots above those carrying the seat supporters 14 and the back frame may rest against said stretcher instead of against the seat supporters whereby a separate adjustment of the back may be attained.

It will be understood that I do not limit this invention to the exact construction or design herein shown, neither do I limit it to any of the details of construction of the supporting or actuating members or slots.

What I claim as my invention is;

1. In a chairof the character described, a chair body, a seat frame at or near its forward end pivotally hung to said chair body, means for supporting the rear of said seat frame in different positions vertically of said body, a back frame supported by said seat frame, a member pivoted to the lower end of said back frame and provided with a series of engaging elements, and an agent on said seat frame with which said engaging elements are adapted to contact whereby said back frame may be moved to and held in different positions.

2. In a chair of the character described, a chair body, a seat frame pivotally connected at or near its forward end to said body, an agent pivotally connected to said seat frame for supporting the rear end of said seat frame in different positions vertical of said body, a back frame supported at its lower end by said seat frame and means for securing the lower end of said back frame to different positions along said seat frame.

3. In a chair of the character described, a chair body, a seat frame adjustably connect ed at its forward and rear ends to said body, an adjustable back frame supported by said body and said seat portion, a member pivotally connected to the lower end of said back frame and an agent carried by said seat frame and with which said member is adapted to engage whereby the lower end of said back frame may be moved to and held in different positions along said seat frame.

4. In a chair of the character described, a body portion, a seat frame pivoted at or near its forward end to said body portion, an agent pivotally connected to said seat frame and to said body portion for supporting the rear end of said seat frame in different positions vertical to said seat frame, a back frame supported by said body portion and said seat frame and a member pivotally connected to the lower end. of said back frame whereby the lower end of said back frame may be moved longitudinally of said seat frame and held in different positions along it.

5. In a chair of the character described, a chair body, a seat frame pivotally hung at or near its forward end to said body, means for supporting the rear end of said seat frame in different positions relative to said body, a back frame supported by said body and at its lower end by said seat frame, a member pivoted to the lower end of said back frame and an agent on said seat frame with which said member is adapted to engage whereby said back frame may be moved to and held in different positions.

6. In a chair of the character described, a chair body, a seat frame pivotally hung at or near its forward end to said body, means for supporting the rear end of said seat frame in different positions relative to said body, a back frame supported by said. body and at its lower end by said seat frame, a member pivoted to the lower end of said back frame and provided with a plurality of slots and a pin carried by said seat frame and adapted to engage one or another of the slots of said member whereby said seat frame may be moved to and held in different positions.

7. In a chair of the character described, a body, a seat frame pivotally hung and adjustably connected to said chair body at or near its forward end, means for supporting the rear end of said seat frame in different positions relative to said body, an adjustable back frame supported by said body and at its lower end by said seat frame, a member secured to said back frame and provided with a plurality of slots and a pin carried by said seat frame and adapted to engage one or another of the slots of said member whereby said back frame may be moved to and held in different positions.

In testimony whereof, I affix my signature, in presence of two witnesses.

OTTO L. OSTENDORF.
